4. Discussion:
It`s very important to understand the difference between
HARD and SOFT joint.
Break Time and Hard Joint
ATTENTION:
If you set Hard joint, Ramp, Torque range and Speed are
disabled. The speed depends on the torque selected and it
is automatically calculated by the unit.
Hard Joint refers to the screws that required few degrees
to be tightened. In this case high speed is dangerous for
the operator a clutchless screwdriver. If you set Break time
at 0 second the system will automatically start at the final
speed. If you set Break Time, the speed will have two
steps: it starts at max speed to approach quickly and then
it reduces the speed to screw. So it increases the precision
and reduces the danger for the users.
-1- Example of automatically speed change.
X = Time in second,
Y = Speed in Rpm
The type of joint (hard or soft) depends on the degrees the
screw needs to be tightened. A soft joint requires 720°. An
hard joint requires 30°. In the next graphic it is possible to
see that hard joint (-2-) requires less degrees to increase
the torque.
Simple to find the kind of joint is this process:
I. Tighten manually the screw until it arrives to support the
head of the screw to the piece
II. Start tightening manually the screw.
III. If manually the operator made a quarter-turn the joint is
hard, over a quarter-turn the joint is soft.
HARD mode automatically set the best speed for the torque
you set.
-2- Example of Hard-Soft joint.
X = Degrees,
Y = Torque in Nm.
Torque/angle difference between HARD / SOFT joint.
5. Connection:
On the back panel, there is one connector for Input and
Output signals.
